Any file system or other application storage layout that you have created on the
volume can be resized after you have grown the volume.
See “Resizing volumes online” on page 78.
Creating a clone storage pool
Assuming that you also want to create full-sized snapshots of application volumes
in mypool that can be moved into a different disk group, the following command
creates a clone storage pool, myclpool, in the same disk group as mypool:
# vxpool -g mydg create myclpool \
dm=mydg09,mydg10,mydg11,mydg12 \
autogrow=pool pooldefinition=mirrored_volumes
This pool supports the creation of mirrored volumes. It also has a non-default
autogrow policy that prevents it aggregating disks from the disk group outside
the pool.
See “Preparing storage pools for full-sized instant snapshots” on page 99.
Preparing a full-sized snapshot volume
Before you can take a full-sized snapshot of an application volume, you must
prepare the empty volume that is to become the snapshot volume as shown in the
following command:
# vxassist -g mydg -P myclpool make mysnpvol 2g type=snapshot\
init=active
This command automatically associates a data change object (DCO) and DCO
volume with the volume.
See “Creating a volume for use as a full-sized instant or linked break-off snapshot”
on page 100.
Taking a full-sized snapshot of an application volume
Having prepared an empty volume, you can take a snapshot of the application
volume as shown in the following command:
# vxsnap -g mydg make source=stmrvol/snapvol=mysnpvol/syncing=on
The following command starts a full synchronization of the snapshot volume,
and blocks until this is complete:
